V,Specification of Letters Patent.

Application led January 21, 1920. Serial No. 353,000.

To all whom t may concern.-

Be itknown that I, FRAK STOKLOSA, a citizen of Poland, residing atChicago, in the county oi" Cook and State of Illinois, have inventedcertain new and useful Improvements in Pumps, specilication.

The primary object of the present invention resides in the provision or"a pump of the lift type wherein the piston within the pump cylinder forelevating the water is raised and lowered by an oscillatory movement ofan operating handle operatively connected to the piston.

of which the following is a A further object of the invention is toassociate a lweighted lever with a lift pump to equalize pressure duringthe raising and lowering movement of the pump piston.

Vith the above and other objects in view, the invention consists in thenovel form, combination and arrangement of parts herein fully describedand shown in the accompanying drawing, wherein like reference charactersindicate similar parts throughout the several views.

Inthe drawings,

Figure 1 is a front elevational view of a lift pump constructed inaccordance with the present invention, the lower portion of the pumpcylinder being broken away,

Fig. 2 is a vertical cross sectional view of the pump shown in Fig. 1showing the lift piston within the pump cylinder,

Fig. 3 is a cross sectional view taken on line lll-III of Fig. 2 withthe valve positioned above the piston head, and

Fig. t is a cross sectional viewV taken on line IV-IV of Fig. 2 with aportion of the piston head broken away.

The invention relating to water pumps of the lift type, there isillustrated a pump cylinder 5 adapted for sinking in a well with thehead 6 of the cylinder secured to the well cover 7 by the lateral flange8 shown more clearly in Fig. 1, while an outlet spout 9 arrangedadjacent the upper end of the cylinder head 6 is adapted for thedelivery ot water Jfrom the pump cylinder.

rfhe mechanism for elevating the water in the pump cylinder 5` embodiesa hollow piston 10 of the form best illustrated in Fig. 2, the pistonand cylinder being preferably rectangular in cross section to preventrelative rotary movement between the parts. The upper end 10 of thepiston 10 is provided with water passage openings 11 that are normallyclosed by a flat valve 12 shown in Figs. 3` and 4, the valve 12 having acentral opening therein to loosely receive the central boss 13 in thetop 10 of the piston. Guide pins 111 extending vertically from the upperend 10 of the piston form guides for the vertical movements of the flatvalve 12 while the heads of said pins 14 limit the upward movement ofthe valve. A piston rod 15 is connected to the piston boss 13 andprojects upwardly of the head 6 of the pump.

In order to effect a reciprocation of the piston 10 within the pumpcylinder 5, there is provided a frame mounted upon the pump head 6 whichcomprises vertical bars 16 and 17 between which the lever beam 18 ispivoted as at 19, an adjustable weight 20 being mounted on each end ofthe lever beam 18 for purposes of weighting and counterbalancing thesame. A vertical end extension 21 is carried by the lever beam 18, beingbraced as at 21 and has a lateral extension 22 connected by a cord orcable 28 to the upper end of the piston rod 15, the cord 23 passing overa pulley 24 mounted in thc bearing 25 at the upper end of the side bars16 and 17. A sprocket wheel 26 operated by a crank 27 is journaled onthe front face ot' the cylinder head 6 and a point above the outletspout 9 while sprocket wheels 28 are j ournaled at opposite sides of thespout, and over all of which sprocket wheels passes a sprocket chain 29with the ends connected to cords 30 carried by opposite ends of thelever beam 18.

In the operation of the pump, the crank handle 27 is oscillated tofollow the path shown by the curved arrow line in Fig. 1 to effect arising and lowering of the opposite ends of the lever beam 18 with aconsequent rise and fall of the piston 10 within the cylinder 5. Duringthe lowering movement of the piston, caused by its end weight when thearm extension 21 of the lever beam is elevated, the valve 12 movesvertically upon the pins 111 to permit the water in the lower end of thecylinder to pass through the piston openings 11, while during a reversemovement of the lever beam 18, with the rise of the piston 10, the valve12 seats directly upon the upper end 10 of the piston to elevate thewater within the cylinder above the piston for delivery by way of theoutlet spout 9. The adjustable weights 20 upon the lever beam 18 insurean easy operation of the pump by counterbalancing the Patented July 20,1920.
